This calculator uses a two-samplettest, which compares two datasets to see if their means are statistically different. That is different from aone samplettest, which compares the mean of your sample to some proposed theoretical value. The most general formula for attest is composed of two means...

This simple confidence interval calculator uses a t statistic and two sample means (M1 and M2) to generate an interval estimate of the difference between two population means (μ1 and μ2).The formula for estimation is:μ1 - μ2 = (M1 - M2)± ts(M1 - M2)where:...
Here you can not only easily perform one-sample t-tests, but also two-sample t-tests, as well as paired t-tests. Do you prefer to find the p-value from t-test, or would you rather find the t-test critical values? Well, this t-test calculator can do both! 😊 What does a t-...
Use the t-statistic calculator (t-value calculator or t test statistic calculator) to compute the t-value of a given dataset using its sample mean, population mean, standard deviation and sample size. Read further where we answer to the following questions: What is the t-statistic? How do ...
The t-test calculator, work with steps, formula and practice problems would be very useful for grade school students (K-12 education) to learn what is appropriate test statistic for t-Test, how to find it. With this statistics and probability tool, we can effortlessly make student's t-dist...
where x is the sample mean, μ is the population mean, s is the standard deviation of the sample, n is the sample size, and t is the t statistic. Which statistic should I use - the t-score or the mean score"? The t-distribution calculator accepts two statistics as input: a t-...
Two Sample t-test 两样本t检验用于检验两个总体的均值是否相等。两总体都是未知的,且我们不想或不易测量出总体所有的个体,来求得总体均值。所以我们从总体中随机抽样得到样本。对两样本进行统计检验,来看两样本差异是否显著。 案例 若我们想知道两个不同物种的乌龟的平均重量是否相等。我们可以进行随机抽样选择部分...
t-Test Calculator is a tool used to determine whether there is a statistically significant difference between the means of two independent groups. What is a t-Statistic? The t-Statistic is a value derived from your sample data that measures the size of the difference relative to the variation...
